    OPINION
    ERVIN, Circuit Judge:
    The National Science Foundation ("NSF") appeals from an order
    requiring the agency to comply with subpoenas issued by an arbitrator
    during prehearing discovery. The subpoenas demanded that the
    agency, which was not a party to the arbitration agreement, produce
    documents and employee testimony related to a construction contract
    between appellee COMSAT, Inc. ("COMSAT"), and an NSF
    awardee. We reverse the district court's order and hold as follows: (1)
    The Federal Arbitration Act, 9 U.S.C.A. §§ 1-307 (West 1999) (the
    "FAA"), does not authorize an arbitrator to subpoena third parties dur-
    ing prehearing discovery, absent a showing of special need or hard-
    ship; (2) when the government is not a party to the underlying action,
    an agency's refusal to comply with a subpoena must be reviewed
    under the standards established for final agency actions by the
    2
    Administrative Procedure Act ("APA"), 5 U.S.C.A. §§ 702 - 8301
    (West 1996 & Supp. 1999); and (3) NSF did not violate its own regu-
    lations or the APA when the agency decided not to comply with the
    subpoenas at issue in this case.
    I.
    Appellant NSF is the government agency charged with supporting
    much of this nation's federally-funded basic science and engineering
    research. See 42 U.S.C.A. § 1862(a) (West 1994). In accordance with
    its congressional mandate, NSF awards grants and fellowships to
    researchers and enters contractual or cooperative agreements with
    research institutions.1 The agency does not engage directly in scien-
    tific research. See 42 U.S.C.A. §§ 1862(a)-(c).
    Associated Universities, Incorporated ("AUI") is a not-for-profit
    corporation organized for the purpose of conducting scientific
    research and education. In 1988 AUI entered a cooperative agreement
    with NSF, by the terms of which AUI agreed to administer the
    _________________________________________________________________
    1 Section 6305 of the Federal Grant and Cooperative Agreement Act of
    1977, 31 U.S.C.A. §§ 6301 - 6308 (West 1983 & Supp. 1999), explains
    the nature and purpose of a cooperative agreement:
    An executive agency shall use a cooperative agreement as the
    legal instrument reflecting a relationship between the United
    States Government and a ... recipient when --
    (1) the principal purpose of the relationship is to transfer a
    thing of value to State, local government, or other recipient
    to carry out a public purpose of support or stimulation autho-
    rized by a law of the United States instead of acquiring (by
    purchase, lease, or barter) property or services for the direct
    benefit or use of the United States Government; and
    (2) substantial involvement is expected between the execu-
    tive agency and the State, local government, or other recipi-
    ent when carrying out the activity contemplated in the
    agreement.
    31 U.S.C.A. § 6305.
    The statute distinguishes between "procurement contracts" and "coop-
    erative agreements." See §§ 6303, 6305.
    3
    National Radio Astronomy Observatory, a network of research tele-
    scopes. The cooperative agreement imposed no obligation upon NSF
    or the government to fund AUI operations beyond the upper limits of
    the award, which was provisional and subject to congressional appro-
    priations. NSF retained the right to terminate the agreement due to a
    lack of available funds or for other reasons. The agreement also speci-
    fied that in the absence of written notice to the contrary from NSF's
    Grants and Contracts Officer, "the Government shall not be obligated
    to reimburse the Awardee for any costs in excess of the total amount
    then allotted to the agreement."
    On October 19, 1990, AUI entered into a contract with COMSAT2
    to build a state-of-the art radio telescope in Green Bank, West Vir-
    ginia (the "Green Bank telescope"), at a cost of $55 million. Some
    years later, in October of 1997, a dispute arose between the parties
    over AUI's liability for cost overruns. COMSAT claimed that various
    acts and omissions by AUI, including after-the-fact changes to the
    telescope specifications, entitled the contractor to $29 million in addi-
    tional costs. The contract between AUI and COMSAT contained a
    mandatory arbitration clause, and pursuant to the contract, the parties
    submitted the claim to the American Arbitration Association for reso-
    lution.
    At COMSAT's request, on July 10, 1998, the arbitrator issued a
    subpoena to NSF requiring the agency to produce all documents
    related to the Green Bank telescope. NSF declined to comply with
    this subpoena. The agency responded in writing to COMSAT's coun-
    sel, justifying its decision not to comply with citations to NSF regula-
    tions governing subpoenas.3 See 45 C.F.R. § 615.5. By way of further
    _________________________________________________________________
    2 COMSAT's predecessor corporation, Radiation Systems, Inc., was
    the original party to this agreement.
    3 Pursuant to 5 U.S.C.A. § 301, executive branch agencies may pre-
    scribe regulations for their own internal governance, conduct of business,
    record keeping, and document custody. Such regulations are commonly
    known as "housekeeping" regulations, and do not authorize the agency
    to withhold information from the public. Housekeeping regulations that
    create agency procedures for responding to subpoenas are often termed
    "Touhy regulations," in reference to the Supreme Court's decision in
    United States ex rel. Touhy v. Ragen, 
    340 U.S. 462
    (1951). In Touhy the
    Court ruled that agency employees may not be held in contempt for
    refusing to answer a subpoena, if prohibited from responding by a supe-
    rior. See 
    id. at 468.
    4
    explanation, NSF noted in this letter that COMSAT had already
    sought substantially the same documents with an August, 1997 Free-
    dom of Information Act ("FOIA") request. See 5 U.S.C.A. § 552(a)
    (West 1996 & Supp. 1999). NSF had suspended its efforts to comply
    with that voluminous request because COMSAT had been delinquent
    in paying the associated photocopying charges.4
    On August 20, 1998, COMSAT moved the arbitrator to issue the
    three subpoenas that are the subject of this litigation. One of these
    subpoenas required the NSF's "Document Custodian" to appear and
    to produce "[a]ll documents relating to the Green Bank Telescope
    project."5 The two additional subpoenas ordered NSF employees Rob-
    ert Dickman, a liaison to AUI for the telescope program, and Hugh
    Van Horn, Dickman's supervisor and a former member of the AUI
    board of trustees, to appear and produce all documents in their posses-
    sion related to the telescope project. The subpoenas were issued
    returnable to COMSAT's counsel.
    NSF responded on August 25, 1998, with a letter to COMSAT
    indicating that the agency's prior decision not to produce documents
    was a final agency decision. This letter also described the agency's
    analysis of the relevant considerations under its housekeeping or
    "Touhy" regulations.
    Pursuant to NSF's Touhy regulations, when responding to a sub-
    poena in a legal proceeding to which the NSF is not a party, NSF's
    General Counsel must consider the following:
    (1) Whether allowing testimony and document production
    would serve the stated purposes of the regulation
    _________________________________________________________________
    4 NSF states that it identified over 40 linear feet of files that might con-
    tain documents responsive to COMSAT's initial FOIA request, and that
    processing such a request would cost more than $20,000. When so
    informed, COMSAT agreed to narrow its request, and NSF continued to
    produce responsive documents until June of 1998.
    5 In its brief COMSAT states that its subpoenas sought only a "small
    set" of documents not already produced by NSF or AUI. As worded,
    however, the subpoenas plainly seek "all documents" in NSF's posses-
    sion that are in any way related to the telescope project.
    5
    (these are promoting efficient NSF operations, avoid-
    ing the involvement of NSF in tangential and contro-
    versial issues, maintaining NSF impartiality in relation
    to private litigants, and protecting sensitive, confiden-
    tial information and the agency's deliberative process);
    (2) Whether allowing testimony or document production is
    necessary to prevent a miscarriage of justice;
    (3) Whether NSF has an interest in the decision that will
    be rendered in the legal proceeding; and
    (4) Whether compliance with the subpoena is in the best
    interests of NSF and the United States.
    See 45 C.F.R. § 615.5(b).
    NSF's General Counsel concluded in his written response to COM-
    SAT that NSF would not produce the subpoenaed documents. The
    Counsel's Touhy analysis reached these conclusions:
    (1) Production of the documents would be uneconomical,
    as the demand is substantially duplicative of COM-
    SAT's earlier FOIA request;
    (2) Production would be unnecessarily burdensome
    because many of the documents originated from AUI
    and may be discovered from that organization;
    (3) NSF has no indemnity or joint defense agreement with
    AUI, so production would not further the goal of main-
    taining NSF's neutrality as a third party;
    (4) Because the documents are available via FOIA or
    through AUI, compliance is unnecessary to prevent a
    miscarriage of justice; thus,
    (5) The balance of NSF's and the public's interests favor
    non-compliance.
    6
    In this same August 25, 1998, letter to COMSAT's counsel, NSF
    requested further clarification of COMSAT's justification for seeking
    to depose Van Horn and Dickman. COMSAT responded with the
    explanation that these NSF employees had discussed the Green Banks
    project with AUI officials. NSF responded in turn with a request for
    additional clarification from COMSAT, and in a September 28, 1998,
    letter the agency indicated that it had not reached a final decision with
    respect to the deposition subpoenas. COMSAT then petitioned the
    federal district court to compel NSF's compliance.
    On December 4, 1998, NSF and COMSAT argued the motion to
    compel before a magistrate judge. COMSAT insisted that by naming
    NSF in the caption of its motion, it had made the agency a party to
    the underlying dispute and thereby subjected it to the requirements of
    Federal Rule of Civil Procedure 45 governing responses to a sub-
    poena. See Fed. R. Civ. P. 45. The magistrate judge accepted this
    argument and ruled from the bench that NSF could not assert sover-
    eign immunity as a defense to enforcement of the subpoenas.
    The magistrate judge concluded further that NSF had waived its
    right to object to the subpoenas because the agency had ignored its
    own regulations, which state
    [i]f a response to a demand is required before the General
    Counsel has made the determination [whether to respond]
    . . . the General Counsel shall provide the court or other
    competent authority with a copy of this part, inform the
    court or other competent authority that the demand is being
    reviewed, and seek a stay of the demand pending a final
    determination.
    45 C.F.R. § 615.6(c). The magistrate judge then entered an order
    requiring NSF to comply with the COMSAT subpoenas.
    NSF immediately appealed this order to the district court. On Janu-
    ary 8, 1999, the parties appeared for a hearing at which the NSF
    argued that the court should reject the magistrate's finding of waiver
    because the agency had effectively lodged a Rule 45 objection
    through its letters to COMSAT. NSF also argued that the FAA does
    not grant an arbitrator the authority to subpoena third parties for pre-
    7
    arbitration discovery; that the agency's actions must be reviewed
    under the standards of the APA; and that, at least with respect to the
    deposition subpoenas, jurisdiction was lacking because the agency
    had not reached a final decision regarding compliance.6
    The district court read the FAA as a broad grant of full subpoena
    power to arbitrators. The court reviewed NSF's refusal to comply
    with the arbitration subpoenas under the standards of the Federal
    Rules of Civil Procedure. Because the NSF did not seek judicial relief
    before the return date for the subpoenas, the court found that the
    agency had violated its own Touhy regulations and thereby waived
    any right to object or to seek a protective order. The court then
    affirmed the ruling of the magistrate judge.
    II.
    The situs of the pending arbitration is Reston, Virginia; therefore
    the district court for the Eastern District of Virginia properly assumed
    jurisdiction pursuant to § 7 of the FAA. See 9 U.S.C.A. § 7 (West
    1999). Our jurisdiction over an appeal from the court's order enforc-
    ing the subpoenas arises from 28 U.S.C.A. § 1291 (West 1993).
    At the outset, we note that although our review of the district
    court's legal conclusions is de novo, see Burgin v. Office of Personnel
    Management, 
    120 F.3d 494
    , 497 (4th Cir. 1997), our review of NSF's
    refusal to comply with the subpoenas is governed by the Administra-
    tive Procedure Act ("APA"). See 5 U.S.C.A. §§ 702, 704, 706 (West
    1996). When the government is not a party, the APA provides the sole
    avenue for review of an agency's refusal to permit its employees to
    comply with subpoenas. See Smith v. Cromer, 
    159 F.3d 875
    , 881 (4th
    Cir. 1998) ("Cromer's remedy, if any, for the Justice Department's
    [refusal to permit its employees to testify] may be found in the [APA]
    . . . . ").
    _________________________________________________________________
    6 NSF also argued that the COMSAT subpoenas, which lacked instruc-
    tions on how to challenge a subpoena, were facially defective when
    judged by the standards of Rule 45. Because we reverse on other
    grounds, we do not reach the issue of alleged defects in the subpoenas.
    8
    The APA waives the government's sovereign immunity from suit
    and permits federal court review of final agency actions, when the
    relief sought is other than money damages and the plaintiff has stated
    a claim "that an agency or an officer or employee thereof acted or
    failed to act in an official capacity . . . ." 5 U.S.C.A. § 702. As the
    Supreme Court has instructed, an agency action may be considered
    "final" only when the action signals the consummation of an agency's
    decisionmaking process and gives rise to legal rights or conse-
    quences. See Bennett v. Spear, 
    520 U.S. 154
    , 177-78 (1997). A
    reviewing court may set aside a final agency action when the action
    is arbitrary, capricious, an abuse of discretion, or otherwise not in
    accordance with the law. See 5 U.S.C. § 706.
    Additionally, we preface our analysis with the observation that,
    despite COMSAT's attempts to characterize NSF as a party-in-
    interest in the arbitration proceeding, NSF was not a party to the
    Green Bank telescope contract and is not liable to pay any judgment
    that the arbitrator might award.7 Moreover, the arbitration hearing had
    not yet commenced when the subpoenas issued. Thus, this case tests
    the scope of an arbitrator's authority, pursuant to the FAA, to sub-
    poena witnesses and documents from a third-party federal agency for
    the purpose of pre-hearing discovery.
    A.
    Before we assert subject matter jurisdiction in this case we must
    decide whether any of NSF's responses to the subpoenas were "final"
    agency actions. See 5 U.S.C.A. § 704 (limiting review to "[a]gency
    action made reviewable by statute and final agency action . . .").
    Prior to the return date for the document subpoenas, NSF's general
    _________________________________________________________________
    7 COMSAT cites the minutes of the meeting of the board of AUI trust-
    ees for the company's claim that NSF is obligated to pay any arbitration
    award. These minutes actually state that while litigation and award
    expenses are an "allowable cost" under the cooperative agreement,
    NSF's obligation to secure funding for these costs"is subject to the
    requirement that the Director [of NSF], in his or her sole discretion, shall
    determine the appropriateness of the reimbursement of the costs." See
    Joint Appendix at 108.
    9
    counsel advised COMSAT in writing that the agency would not pro-
    duce the materials demanded. This was a final agency action that is
    ripe for our review under the APA.
    Prior to the date scheduled for Van Horn and Dickman's deposi-
    tions, NSF notified COMSAT's counsel that the agency required
    additional information to decide whether to allow its employees to
    comply with the subpoenas issued to them. NSF subsequently stated
    in its brief to this Court that the agency has not reached a final deci-
    sion as to whether to permit its employees to comply with the deposi-
    tion subpoenas. Yet during oral argument NSF's counsel appeared to
    concede that the agency had in fact reached a final decision not to
    permit its employees to testify. Counsel then invited this Court to
    review that decision.
    Ordinarily we would consider whether the decision as it was
    announced by counsel at oral argument was sufficiently "final" to per-
    mit review, before we would proceed to address the merits of the
    agency's action. Further analysis of this issue is unnecessary, how-
    ever. We may assume without deciding that NSF reached a final deci-
    sion not to comply with the deposition subpoenas because our holding
    turns, not on finality or lack thereof in this particular agency action,
    but rather on the scope of an arbitrator's subpoena power under the
    FAA.
    B.
    The subpoena powers of an arbitrator are limited to those created
    by the express provisions of the FAA. The statute provides, in perti-
    nent part:
    arbitrators . . . may summon in writing any person to attend
    before them or any of them as a witness and in a proper case
    to bring with him or them any book, record, document, or
    paper which may be deemed material . . . .
    9 U.S.C.A. § 7.
    Nowhere does the FAA grant an arbitrator the authority to order
    non-parties to appear at depositions, or the authority to demand that
    10
    non-parties provide the litigating parties with documents during pre-
    hearing discovery. By its own terms, the FAA's subpoena authority
    is defined as the power of the arbitration panel to compel non-parties
    to appear "before them;" that is, to compel testimony by non-parties
    at the arbitration hearing. See 
    id. In disregard
    of the plain language of the statute, COMSAT cites a
    provision of the FAA that permits a federal district court to enforce
    an arbitrator's subpoena, see 9 U.S.C.A.§ 7, seemingly for the propo-
    sition that an arbitrator's subpoena authority is coextensive with that
    of a federal court. This is decidedly not the case. The FAA provides
    that a federal court may "compel the attendance of [a subpoenaed per-
    son] before said arbitrator . . . ." 9 U.S.C.A. § 7 (emphasis added).
    The enforcement provision does not expand the arbitrator's subpoena
    authority, which remains simply the power to compel non-parties to
    appear before the arbitration tribunal.
    Furthermore, once subpoenaed by an arbitrator the recipient is
    under no obligation to move to quash the subpoena. By failing to do
    so, the recipient does not waive the right to challenge the subpoena
    on the merits if faced with a petition to compel. 8 The FAA imposes
    no requirement that a subpoenaed party file a petition to quash or oth-
    erwise challenge the subpoena; the Act's only mechanism for obtain-
    _________________________________________________________________
    8 The district court found that NSF waived its right to object to the sub-
    poenas because the agency did not act pursuant to 45 C.F.R. § 615.6(c),
    which requires NSF to notify the court "or other competent authority"
    that a subpoena is being reviewed and to seek a stay pending a final
    agency determination. 
    Id. NSF argues
    that COMSAT requested that such
    notice be given to COMSAT's counsel, not the arbitrator, and the agency
    acted accordingly.
    We need not settle this procedural squabble. NSF's compliance with
    its own Touhy regulations, which protect its employees from contempt
    proceedings, has no bearing on the agency's right to object to the arbitra-
    tor's subpoena. See § 615.1(d) (stating that these regulations "may not be
    relied upon to create any right or benefit, substantive or procedural,
    enforceable at law by a party against the United States"). See also 
    Smith, 159 F.3d at 880
    (holding that the Justice Department's Touhy regulations
    are intended for internal governance only and do not create any right to
    disclosure of agency records).
    11
    ing federal court review is the petition to compel. See 9 U.S.C.A. § 7
    ("[U]pon petition the . . . district court . . . may compel the attendance
    of such person.").
    The rationale for constraining an arbitrator's subpoena power is
    clear. Parties to a private arbitration agreement forego certain proce-
    dural rights attendant to formal litigation in return for a more efficient
    and cost-effective resolution of their disputes. See Burton v. Bush,
    
    614 F.2d 389
    , 390-91 (4th Cir. 1980) ("When contracting parties stip-
    ulate that disputes will be submitted to arbitration, they relinquish the
    right to certain procedural niceties which are normally associated with
    a formal trial."). A hallmark of arbitration-- and a necessary precur-
    sor to its efficient operation -- is a limited discovery process. See 
    id. at 391
    (concluding that limitations on discovery promote the "policy
    underpinnings of arbitration [which are] speed, efficiency, and reduc-
    tion of litigation expenses."). Consequently, because COMSAT and
    AUI have elected to enter arbitration, neither may reasonably expect
    to obtain full-blown discovery from the other or from third parties.
    Yet COMSAT argues quite persuasively that in a complex case
    such as this one, the much-lauded efficiency of arbitration will be
    degraded if the parties are unable to review and digest relevant evi-
    dence prior to the arbitration hearing. For this reason, in Burton we
    contemplated that a party might, under unusual circumstances, peti-
    tion the district court to compel pre-arbitration discovery upon a
    showing of special need or 
    hardship. 614 F.2d at 391
    .
    We do not now attempt to define "special need," except to observe
    that at a minimum, a party must demonstrate that the information it
    seeks is otherwise unavailable. COMSAT did not attempt to make
    such a showing before the district court, and we infer from the record
    that no such showing would be possible. As COMSAT acknowl-
    edged, many if not all of the documents it sought were obtainable
    from AUI or with a FOIA request. In fact, the record indicates that
    prior to filing its petition to compel, COMSAT obtained hundreds of
    responsive documents from NSF via the FOIA process, continuing up
    to the point when COMSAT abandoned its FOIA request by ceasing
    to pay photocopying charges. Likewise, COMSAT has not attempted
    to show that any information it might obtain from Van Horn and
    12
    Dickman, both employees of non-party NSF, is otherwise unavailable
    from opposing party AUI.
    C.
    Assuming arguendo that COMSAT could yet make the requisite
    showing of special need, we examine whether the NSF's refusal to
    comply with the COMSAT subpoenas was an arbitrary and capricious
    agency action taken in violation of the APA. We apply the APA's
    deferential standard of review in full recognition of the fact that one
    of our sister circuits has decided otherwise. In Exxon Shipping Co. v.
    U.S. Dept. of Interior the Ninth Circuit held that non-party federal
    agencies must produce evidence in response to the subpoenas of pri-
    vate litigants, subject only to the court's discretionary right to limit
    burdensome discovery under Rules 26 and 45 of the Federal Rules of
    Civil Procedure. 
    34 F.3d 774
    , 778-779 (9th Cir. 1994). We decline to
    follow this holding.
    1.
    COMSAT does not contest the underlying validity of NSF's Touhy
    regulations. Instead, COMSAT maintains that such housekeeping reg-
    ulations do not "immunize" an agency from the duty to comply with
    a federal subpoena. We agree, but only in the following respect: it is
    sovereign immunity, not housekeeping regulations, that gives rise to
    the Government's power to refuse compliance with a subpoena. As
    we have acknowledged, "subpoena proceedings fall within the protec-
    tion of sovereign immunity even though they are technically against
    the federal employee and not against the sovereign," Boron Oil Co.
    v. Downie, 
    873 F.2d 67
    , 71 (4th Cir. 1989); thus, in the context of an
    agency's response to a third-party subpoena, "the proper method for
    judicial review of the agency's final decision pursuant to its regula-
    tions is through the Administrative Procedure Act." United States v.
    Williams, 
    170 F.3d 431
    , 434 (4th Cir. 1999). The APA waives sover-
    eign immunity and permits a federal court to order a non-party agency
    to comply with a subpoena if the government has refused production
    in an arbitrary, capricious, or otherwise unlawful manner. See 
    id. (holding that
    the APA is the only avenue of review for a state crimi-
    nal defendant aggrieved by Justice Department's refusal, pursuant to
    13
    internal housekeeping regulations, to provide the defense with FBI
    files).
    The Ninth Circuit's Exxon decision abrogates the doctrine of sover-
    eign immunity to a significant degree. Although the decision
    acknowledges the APA as the source of the congressional waiver of
    sovereign immunity permitting review of a non-party agency's refusal
    to comply with a subpoena, 
    see 34 F.3d at 779
    n.9, Exxon overlooks
    an important limitation upon this waiver: courts may reverse an agen-
    cy's decision not to comply only when the agency has acted unrea-
    sonably. See Fishermen's Dock Coop., Inc. v. Brown, 
    75 F.3d 164
    ,
    168 (4th Cir. 1996) ("[C]ourt of appeals review looks to the agency's
    action to determine whether the record reveals that a rational basis
    existed for its decision") (citation omitted).

    Acting in accordance with the procedures mandated by its regula-
    tions, NSF reached an entirely reasonable decision to refuse compli-
    ance with COMSAT's document subpoenas. In an August 25, 1998,
    letter to COMSAT, NSF's general counsel described in detail the
    agency's Touhy analysis of the costs and benefits associated with pro-
    ducing the subpoenaed documents. Most if not all the documents
    sought were available through COMSAT's FOIA request or from
    AUI; therefore NSF's counsel concluded that production would be
    unnecessarily duplicative and costly. As an agency official must,
    NSF's counsel also considered whether the public interest and the
    agency's taxpayer-funded mission would be furthered by compliance.
    NSF's counsel answered this question in the negative, and we can-
    not quarrel with his conclusion. Compliance with the third-party sub-
    poenas issued in this single case, where the litigant sought a
    tremendous number of agency documents and demanded the presence
    of agency employees at depositions, would measurably strain agency
    resources and divert NSF personnel from their official duties. Multi-
    ply the cost of compliance by the number of NSF grantees -- almost
    twenty thousand -- who might become embroiled in similar disputes,
    or by the limitless number of private litigants who might seek to draw
    upon NSF's expertise, and the potential cumulative burden upon the
    agency becomes alarmingly large.
    14
    When an agency is not a party to an action, its choice of whether
    or not to comply with a third-party subpoena is essentially a policy
    decision about the best use of the agency's resources. We find NSF's
    decision reasonable in this case, and so we defer to the agency's judg-
    ment, recognizing as we do that "federal judges-- who have no con-
    stituency -- have a duty to respect legitimate policy choices made by
    those who do . . . [because] [o]ur Constitution vests such responsibili-
    ties in the political branches." Chevron U.S.A. Inc. v. Natural
    Resources Defense Council, Inc., 
    467 U.S. 837
    , 866 (1984) (citation
    omitted).
    The Ninth Circuit grounded its Exxon decision in a steadfast con-
    viction that "the public . . . has a right to everyman's 
    evidence." 34 F.3d at 779
    (quoting United States v. Bryan, 
    339 U.S. 323
    , 331
    (1950)). Our decision today does not call this important principle into
    question. Private litigants who are dissatisfied with an agency's
    response to a third-party subpoena or to a FOIA request may still
    obtain federal court review under the APA. See 
    Williams, 170 F.3d at 434
    (in an APA action, federal court may compel agency to pro-
    duce information unlawfully withheld or unreasonably delayed).
    Of course, neither FOIA nor a third-party subpoena will provide
    the private litigant with guaranteed access, at public expense, to the
    testimonial evidence of agency employees. When the government is
    not a party, the decision to permit employee testimony is committed
    to the agency's discretion. This compromise between public and pri-
    vate interests is necessary to conserve agency resources and to pre-
    vent the agency from becoming embroiled in private litigation. See
    Distaff, Inc. v. Springfield Contracting Corp., 
    984 F.2d 108
    , 112 n.2
    (4th Cir. 1993).
    III.
    In summary, we hold today that a federal court may not compel a
    third party to comply with an arbitrator's subpoena for prehearing dis-
    covery, absent a showing of special need or hardship. Moreover, if the
    non-party recipient of a subpoena is a government agency, principles
    of sovereign immunity apply. The decision whether to provide docu-
    ments or employee testimony in response to a third-party subpoena is
    committed to agency discretion. Accordingly, we review the govern-
    15
    ment's refusal to comply with such a subpoena under the APA's "ar-
    bitrary and capricious" standard for final agency actions.
    The district court erred in enforcing the arbitrator's subpoenas. The
    court also erred when it reviewed NSF's actions under the standards
    of Federal Rule of Civil Procedure 45, rather than the standard estab-
    lished by the APA. The order enforcing the subpoenas is, therefore,
    REVERSED.
